Genetic divergences and hybridization within the Sebastes inermis complex [PDF]

PeerJ, 2023
The Sebastes inermis complex includes three sympatric species (Sebastes cheni, viz Sebastes inermis, and Sebastes ventricosus) with clear ecomorphological differences, albeit incomplete reproductive isolation.

A common statement on anthropogenic hybridization of the European wildcat (Felis silvestris)

Frontiers in Ecology and Evolution, 2023
Preserving natural genetic diversity and ecological function of wild species is a central goal in conservation biology. As such, anthropogenic hybridization is considered a threat to wild populations, as it can lead to changes in the genetic makeup of ...

Concern over hybridization risks should not preclude conservation interventions

Conservation Science and Practice, 2021
Conservation interventions such as assisted migration and genetic alterations are controversial in part because, through unintended hybridization events, they may imperil native species.

The geometry and genetics of hybridization [PDF]

Evolution, 2019
Abstract We develop an analytical framework for predicting the fitness of hybrid genotypes, based on Fisher’s geometric model. We first show that all of the model parameters have a simple geometrical and biological interpretation. Hybrid fitness decomposes into intrinsic effects of hybridity and heterozygosity, and extrinsic measures of

The genic view of hybridization in the Anthropocene

Evolutionary Applications, 2021
Human impact is noticeable around the globe, indicating that a new era might have begun: the Anthropocene. Continuing human activities, including land‐use changes, introduction of non‐native species and rapid climate change, are altering the ...

Genetic variation and hybridization determine the outcomes of conservation reintroductions

Conservation Letters
The preservation of genetic variation is fundamental in biodiversity conservation, yet its importance for population viability remains contentious.

Reinforcement and the Genetics of Hybrid Incompatibilities [PDF]

Genetics, 2006
Abstract Recent empirical studies suggest that genes involved in speciation are often sex-linked. We derive a general analytic model of reinforcement to study the effects of sex linkage on reinforcement under three forms of selection against hybrids: one-locus, two-locus, and ecological incompatibilities.

Genomic evidence reveals high genetic diversity in a narrowly distributed species and natural hybridization risk with a widespread species in the genus Geodorum

BMC Plant Biology, 2023
Background Understanding genetic diversity is a core issue in conservation genetics. However, previous genetic diversity evaluations of narrowly distributed species have rarely used closely related widespread species as a reference.

Population genomic monitoring provides insight into conservation status but no correlation with demographic estimates of extinction risk in a threatened trout

Evolutionary Applications, 2022
The current extinction crisis requires effective assessment and monitoring tools. Genetic approaches are appealing given the relative ease of field sampling required to estimate genetic diversity characteristics assumed related to population size ...

Genetic evaluation of F2 and F3 interspecific hybrids of mung bean (Vigna radiata L. Wilczek) using retrotransposon‐based insertion polymorphism and sequence‐related amplified polymorphism markers

Indonesian Journal of Biotechnology, 2023
Mung bean (Vigna radiata L. Wilczek) is a self‐pollinating and indispensable pulse crop in Indonesia. While low yield productivity is a major concern, genetic improvement is possible through interspecific hybridization.
